论文摘要
我们构建了一个模型，解释了典型通货膨胀模型中的暗物质，重子不对称和重新加热。引入了三代具有分层质量的右撇子中微子，并引入了导致主动中微子自我相互作用的光标量场。最轻的无菌中微子是在存在新的轻标量场的情况下由多德尔森 - 维德罗机构产生的暗物质候选者，而重力颗粒产生的最重，最重的无菌中微子最重，是最重的无菌中微子，是导致巴里昂不对称的产生的。通过非最小值耦合到标量曲率引起的标准模型HIGGS场的旋转不稳定性实现了加热，这可以解决HIGGS凝结产生的重力和曲率扰动的过度生产。
We construct a model explaining dark matter, baryon asymmetry and reheating in quintessential inflation model. Three generations of right-handed neutrinos having hierarchical masses, and the light scalar field leading to self-interaction of active neutrinos are introduced. The lightest sterile neutrino is a dark matter candidate produced by a Dodelson-Widrow mechanism in the presence of a new light scalar field, while the heaviest and the next heaviest sterile neutrinos produced by gravitational particle production are responsible for the generation of the baryon asymmetry. Reheating is realized by spinodal instabilities of the Standard Model Higgs field induced by the non-minimal coupling to the scalar curvature, which can solve overproduction of gravitons and curvature perturbation created by the Higgs condensation.
